Structure of piezoelectric diaphragmThe piezoelectric sound element must have a piezoelectric diaphragm.This is a simple structure in which a piezoelectric ceramic adheres to brass or nickel alloy metal plate.Mechanism of producing sound for piezo diaphragmsWhen a voltage is applied to the piezoelec

The soldering temperature and soldering time of the buzzer will directly affect the deformation coefficient of the buzzer, thus affecting the buzzer sound. May cause the buzzer sound to become small, no sound, hoarseness, etc.In order to avoid the above problems, we hope that customers can refer to

Working Principle of Piezo buzzerThe piezo buzzers use piezoelectric materials. Piezoelectric materials create electricity when stress is applied, and become stressed when electricity is applied.The piezo element is to stick the piezoelectric material on the metal sheet. When an alternating voltage

There are two major kinds of buzzers for hobby usage, active and passive. Therefore, the buzzer connected to output gets pulsed beep sound. A passive buzzer requires a signal source that gives the sound signal. If you're still wondering which sort of buzzer to get, just become active buzzers. After

Structure of piezoelectric diaphragmThe piezoelectric sound element must have a piezoelectric diaphragm.This is a simple structure in which a piezoelectric ceramic adheres to brass or nickel alloy metal plate. Mechanism of producing sound for piezo diaphragmsWhen a voltage is applied to the piezoe

Loudness and pitch of soundSound is a vibration of air.Sounder pressure level (dB) = loudness of soundAir pressure is called Sound Pressure when a sound is propagated through the air.Minimal loudness of sound perceived by a human is defined as 0dB (20μPa). Sound pressure that Manorshi’s sound compon

When the sound of the buzzer is not a crisp and simple hum, we will call it a murmur or a broken sound. The cause of the buzzer noise can be divided into two possibilities.First, there are problems with the way of using:The voltage to the buzzer is too high: the diaphragm hits other parts inside the

Active BuzzerIf it is an active buzzer, that is, a buzzer with a drive circuit inside, the voltage used is the DC power supply. For example, the common type MSPS23A35P12 is directly driven by a 12VDC voltage.Passive BuzzerIf it is a passive buzzer, that is, an externally driven buzzer, the voltage u

Buzzer is divided into two kinds, one is active and and another is passive. Active and passive buzzers are used to make sound for electronics. The active buzzer has an internal oscillating source, and the buzzer will sound as soon as it is energized. The active buzzer is widely used in computers, pr

The active piezo buzzer is an integrated electronic sounder that is powered by DC voltage and is widely used in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronics, telephones, timers, etc.
